We need to make sure that SEV-SNP and TDX are not enabled at the same
time. As these two features belong to mutually exclusive hardware
vendors. So, we should make sure that these two features are not enabled
at the same. Thus, a compile time check for it.

Creating some brief documentation for SEV-SNP, summarizing the links on
where to find more information about SEV-SNP, as well as how to build
and run Cloud Hypervisor on it.
This document is a work in progress and will be updated in future PRs
as we add support for it.

This feature flag gates the development for SEV-SNP enabled guest.
Also add a helper function to identify if SNP should be enabled for the
guest.

This is necessary for O_DIRECT based use of raw block devices which may
require access at a larger block size than that of a sector (512 bytes.)

It doens't make sense to limit this to the async_io module and import
across modules so place in default create module.

Assume rax is 0xfee003e0 and the displacement is negative 0x60. The effective
address is then 0xfee00380. This is perfectly valid.
Example instruction:
c7 40 a0 00 10 00 00 movl $0x1000,-0x60(%rax)

Logically until we have handled the first operation the latency is
infinite; this logic was applied to the minimum latency originally but
this patch extends that logic to the maximum and average latency.
To prevent the initial average latency being skewed by the inclusion of
infinity the average value is initally seeded with the first measured
latency.

Since kernel v6.3 the vsock packet is not split over two descriptors
and is instead included in a single one.
This change is based on the discovery and fix identified by Stefano
Garzarella for the vm-virtio vsock implementation and adapted for our
very different codebase.

This commit builds on top of the `Monitor::subscribe` function and
makes it possible to broadcast events published from `event-monitor`
over D-Bus.
The broadcasting functionality is enabled if the D-Bus API is enabled
and users who wish to also enable the file based `event-monitor` can do
so with the CLI arg `--event-monitor`.

There is no need for this struct to be public and since it is used in
this module the #[allow(dead_code)] invocation can be removed.
